ANNEX IU.K.ADMINISTRATIVE PROVISIONS FOR EC TYPE-APPROVAL
4.CONFORMITY OF PRODUCTIONU.K.
4.2.Checking the conformity of the vehicle for a type 1 testU.K.
4.2.1.The type 1 test shall be carried out on a vehicle of the same specification as described in the type-approval certificate. When a type 1 test is to be carried out for a vehicle type-approval that has one or several extensions, the type 1 tests shall be carried out either on the vehicle described in the initial information package or on the vehicle described in the information package relating to the relevant extension.U.K.
4.2.2.
After selection by the approval authority, the manufacturer shall not undertake any adjustment to the vehicles selected.U.K.
4.2.2.1.Three vehicles shall be selected at random in the series and tested as described in Annex III to this Regulation. The deterioration factors shall be used in the same way. The limit values are set out in Tables 1 and 2 of Annex I to Regulation (EC) No 715/2007.U.K.
4.2.2.2.If the approval authority is satisfied with the production standard deviation given by the manufacturer in accordance with Annex X to Directive 2007/46/EC, the tests shall be carried out according to Appendix 1 of this Annex.U.K.
If the approval authority is not satisfied with the production standard deviation given by the manufacturer in accordance with Annex X to Directive 2007/46/EC, the tests shall be carried out according to Appendix 2 of this Annex.
4.2.2.3.
The production of a series shall be deemed to conform or not to conform on the basis of a sampling test of the vehicles once a pass decision is reached for all the pollutants or a fail decision is reached for one pollutant, according to the test criteria applied in the appropriate appendix.U.K.
When a pass decision has been reached for one pollutant, that decision shall not be changed by any additional tests carried out to reach a decision for the other pollutants.
If no pass decision is reached for all the pollutants and no fail decision is reached for one pollutant, a test shall be carried out on another vehicle (see Figure I.4.2).
4.2.3.
Notwithstanding the requirements of Annex III, the tests shall be carried out on vehicles coming straight off the production line.U.K.
4.2.3.1.However, at the request of the manufacturer, the tests may be carried out on vehicles which have completed:U.K.
A maximum of 3 000 km for vehicles equipped with a positive ignition engine;
A maximum of 15 000 km for vehicles equipped with a compression ignition engine.
The running-in procedure shall be conducted by the manufacturer, who shall undertake not to make any adjustments to these vehicles.
4.2.3.2.If the manufacturer wishes to run in the vehicles, (‘x’ km, where x ≤ 3 000 km for vehicles equipped with a positive ignition engine and x ≤ 15 000 km for vehicles equipped with a compression ignition engine), the procedure shall be the following:U.K.
the pollutant emissions (type 1) shall be measured at zero and at ‘x’ km on the first tested vehicle;
the evolution coefficient of the emissions between zero and ‘x’ km shall be calculated for each of the pollutant:
Emissions ‘x’ km/Emissions zero km
This may be less than 1; and
the other vehicles shall not be run in, but their zero km emissions shall be multiplied by the evolution coefficient. In this case, the values to be taken shall be:
the values at ‘x’ km for the first vehicle;
the values at zero km multiplied by the evolution coefficient for the other vehicles.
